The reason for this choice is that
constant - speed races like the Indianapolis 500, which take place on oval tracks, are better for internal combustion engines because those are most efficient at
constant speed, yet waste
fuel and create extra pollution in
stop - start driving.
The
fuel tank is too small and even with the outstanding
fuel mileage, an 8 - gallon tank requires
constant stops to fill up while we are on the road for work.
